Abstract
The present invention provides metal-containing sulfated activator-supports, and polymerization catalyst compositions employing these activator-supports. Methods for making these metal-containing sulfated activator-supports and for using such components in catalyst compositions for the polymerization of olefins are also provided.
Claims21
1-20. (canceled)
A catalyst composition comprising:
- a contact product of a metallocene compound and a metal-containing sulfated activator-support, wherein the metal-containing sulfated activator-support is produced by a process comprising:
- (a) contacting a solid oxide with a sulfate compound to produce a sulfated solid oxide;
- (b) calcining the sulfated solid oxide to produce a calcined sulfated solid oxide;
- and
- (c) contacting the calcined sulfated solid oxide with:
- (i) a transition metal compound and a hydrocarbon solvent;
- or
- (ii) a vapor comprising a transition metal compound;
- to produce the metal-containing sulfated activator-support;
- wherein the metal-containing sulfated activator-support is not calcined.

A catalyst composition comprising:
- a contact product of a metallocene compound and a metal-containing sulfated activator-support, wherein the metal-containing sulfated activator-support is produced by a process comprising:
- (a) contacting a solid oxide with a sulfate compound while calcining to produce a calcined sulfated solid oxide;
- and
- (b) contacting the calcined sulfated solid oxide with:
- (i) a transition metal compound and a hydrocarbon solvent;
- or
- (ii) a vapor comprising a transition metal compound;
- to produce the metal-containing sulfated activator-support;
- wherein the metal-containing sulfated activator-support is not calcined.
